Estimating the standby time of your device
Standby time refers to the amount of time the battery can last when your device is connected to the network but is not in active use, for example, to receive or make phone calls. STAMINA mode, when activated, continuously evaluates the remaining standby time, which can vary depending on how you use your device. STAMINA mode is more effective in lengthening the standby time if you keep the screen of your device locked. If you rarely lock the screen, you may not see much improvement in battery performance.
When you use your device for the first time, the estimated standby time may not be accurate since there is no previous usage history to estimate from.
To view the estimated standby time
1From your Home screen, tap .
2Find and tap Settings > Power management.
Using Low battery mode
You can activate the Low battery mode feature to save power when the battery level is low. This feature helps you to adjust the settings for screen brightness, data traffic and the vibrate function so that you can reduce battery consumption.
